Hi,

First, it’s recommended to upgrade your device to JetPack4.5 for our latest VPI v1.0 release.

To get pitch-linear RGBA data, you can try the pipeline below:

gst-launch-1.0 filesrc location=/opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvideoconvert ! 'video/x-raw(memory:NVMM),format=RGBA' ! dsexample ! nvegltransform ! nveglglessink

If you want an NV12 pitch linear buffer, please try to create the buffer through NvBufSurface before mapping it to VPI image.
You can find a demo of NvBufSurface API below:

Thanks
